Application iled April` 12, 1911, SieraiNo.- 620,:529. Renewed' October 21, 1912. Serial No. 727,083.

To all whom it may concern:

Be it known that I, Louis D. Banner, a citizen of lthe United States, and aresident of the city' of Chicago, county of Cook, and Sta-te oflllinoiahave invented certain new and useful improvements in Lawn Sprinkling Systems, of which the following is a speciication.

My invention relates to improvements in lawn sprinkling systems and has for its object the production of a new and improved distributing valve to be employed 1n the system which shall be simple of construction and eiiicient in operation.

A further object of myinvention is to provide a valy, esst-ated for distributing Water to various raying nozzles and which is capable of being easily controlled by an operator.

Other objects will appeal' hereinafter.

`With theseobjects in view my invention consists in the novel construction and ar rangement of parts all as will be hereinafter more fully described and more nparticularly pointed out in the appended cla1ms.

My invention will be best understood by reference to the accompanying drawing formin a art of this s )ecification and in' P l a Figure 1 is a seotionalview of a lawn and a portion of an adjacently located house in which my improved valve is installed, Fig. 2 is a vertical section of the distributing valve, Fig. 3 is a top plan view of said valve, and Fig. Ll, is a horizontal section taken on line -m of Fig. 2. f

The preferred form of construction of my invention as illustrated in the accompany ing drawing comprises a series of vwater pipes 1, 2 and 3 which are of different lengths and buried in the ground l adjacent the basement 5 of a house as diagrammatically indicated inl Fig. 1. Extending vertically from the ends of the pipes 1, 2 and 3 are pipes 6 the upper ends of which are provided with spraying nozzles 7. Any form oflspraying nozzle may be used, but the rotary type 1s preferred. `The pipes l, 2 and 3 lead from the basement -5 and are connected with the distributing valve, as clearly illustrated in Figs. 2 and 3. The distributing valve issupplied with ywater by a water pipe 8 in which is provided a suitable controlling cock, not shown.

The distributing valve comprises a substantially cylindrical chamber 9the axis of which is vertically disposed. Extending radially from the chamber 9 is a projection 10` in which threaded sockets 11I are provided for thereception of the pipes 1, 2 'and 3. An axially arranged threaded boss 12 is provided on the top ofthe chamber 9 in which a valve stem 13 is journaled, an ordinary stuiiing box 1e being screwed` to the threaded bom l2 for preventing the escape ofWater around the valve stein 13. Said valve stein is provided with a squared extremity 15 to receive an operating key 16. The o era't-ing key 16 may be of any desired length, for instance it may ext-end from the basement of the house to the first or second stories as desired. A truncated conical member 17 is provided in the valve and formed integral with the stem 13 by means of which itis rotated. boredpto fit the exterior surface of the member 17 as clearly illustrated in Fig. 2, the lower edge of the member 17 being formed flush with the lower edge of the chamber 9. In order to retain the member 17 in position in the chamber 9 a sub-member 1S is provided and secured to the chamber `9 ,by means of a threaded ring 19. The ring 19 comprises an inwardly extending flange 2O which engages under a peripheral ange 21 of the member 18. It is apparent from this construct-ion that when hthe ring 19 is screwed securely to the chamber 9 that a tight joint will be formed between the rotary member 17 and the member 18, thus precluding the possibility of any escape of water. The lower end of the member 18 is provided with a pet cock 22 for draining off any impurities or sediment which may collect in the valvc. `The main Water pipe 23 is screwed into the member 18 as illustrated in Fig. 2, said member therefore forming an ante-chamber from which Water is delivered to the space Within the member 17. The periphery of the member 17 is provided with a short circumferential port 24: and an elongated circumferential port 25, these ports being arranged in the same ra dial plane. The sockets 11 in which the pipes j1, 2 and 3 are secured are arranged in communica-tion with ports 26, 27 and 28, these latter registering with the ports 24 und 25 as will be clear by reference to Fig. 2. A small perforation 29 is provided in the top of the member 17 in order to alleviate the friction between the upper surface thereof and the corresponding interior surface oit'` the chamber 9. The friction is lessened by partially balancing the valve, water from the member'17 liowmg through The chamber 9 isA Aio the perforation 29 to the top surface of said member tending to neutralize the water ressure exerted on the upperinterior surf ace of said member. it. will be seen, however, that the perforation 29 cannot. fully balance the valve since the area of the uppermost surface ot' 'the member 17 which 1exerts the pressure downwardly is less than 'the area ott-he surface which exerts an up- -per pressure.

The small difference of pressure is fnf'advanta'e since the desired contactV is maintained etween the periphery of the member u and the `correspmding interior surface of the chamber 9.

The distributing valve 1s operated as fol'- lows: Assuming the member 17 to be in position shown in Fig. il, then the Wat-er will liow 'freely to all of the spraying nozzles 7 which are illustrated in Fig. l. li', however, 1t 1s 4desired to use only'two of the spraying nozzles, then the' ley 18 is turned slightly in one direction. This action will close one of the ports, thel other 'two remaining open. Further movement ofthe-member- 17 will close another port, and still'turther movement willetfect closing 'of all the ports shutting oil the water from all the spraying nozzles. After rot-ation"approximately of 180 d'e- 'grees'ioithe member 17 the port Qe'will come into registration with one of the ports 26, 27 and 28. When' this port 24 is employed only one of' `the spraying nozzles can be used and the'amount of water delivered to said spraying ynozzle can be easily controlled by 'slightly turning the key 1G as will be readily vtmderstood'bv those slrilledjin theart.

' distributing valve'ot the construct-ion set fort-h is'easy of manipulation, simple of construction andieilicient in operation,

While Thave illustrated and described the preferred form ofconstruction for ca`r-I rying my invention into eiiect, this 1s capa-l ble of variations and modications without departing'from' the s irit of the invention. l, therefore, do notvvlsh to be limited to the exact details of construction set fort-h, but desir-etto avail myself ot such variations and modilicationsas comewithin the scope of the appended claims.

Havingl described my invention what I claimas new anddesire to secure by Letters Patent is f I I l. in :z lawn sprinkler system, a valve chamber-'having a trustoconical'bore the axis of which is vertically dis'spfosed, said bore lacing provided with a seriesibf ports lead- 'ing radially therefrom, a plurality of pipe insana? a Water pipe leading into said ante-chamber, a rotary valve tted into the truste-conical bore oizsaid valve chamber and having a. y
